October twenty third，Guangxi Daily focuses on Guangxi Road Construction Group, an enterprise directly under Guangxi Beibu Gulf Investment Group，On the front page《Guangxi Road Construction Group is deeply engaged in the field of asphalt pavement construction technology to break through every 0..01 mm》As the title，It is reported that Guangxi Road Construction Group has been exploring and studying the construction technology of asphalt pavement.，At 100%Hard work and sweat.，Go all out to break through every 0.Remarkable achievements in 01 mm。Expressway from Songwang to the east coast of Tieshangang under construction，Guangxi Road Construction Group set the standard deviation of asphalt pavement flatness 0..366mmA record of，Reached the leading level in Guangxi.；It has been successfully explored and first popularized in Guangxi.“Double bunk”Construction technology of cement stabilized base of pavement；Then the standard deviation of asphalt pavement smoothness is only 0..354 mm，Set a new record for the control of asphalt pavement evenness of expressways in the region，The construction technology level is in the forefront of the country.。If we say that Guangxi Road Construction Group is constantly challenging and surpassing in terms of pavement quality，Then Zhongda anti-segregation Paver is a powerful weapon for Guangxi Road Construction Group to overcome difficult problems.！From 0.389 mm，To 0.366 mm，And then to 0.354 mm……From 2019 to 2023，Zhongda anti-segregation Paver has continuously participated in the asphalt paving of Songwang-Tieshangang East Coast Expressway，Water-stabilized base course of Laidu Expressway“Double bunk”And pavement asphalt paving，Asphalt paving of Daping Expressway。
The medium and large anti-segregation Pavers are used to pave the middle surface course at Songtie Expressway.

The Daxin Expressway from Longzhou to Pingxiang was completed and opened to traffic at the beginning of this year.，Guangxi Road Construction Group, an enterprise directly under Guangxi Beibu Gulf Investment Group№Standard deviation of smoothness of asphalt pavement in Bid Section 3 is only 0.354 mm，Set a new record for the control of asphalt pavement evenness of expressways in the region，The construction technology level is in the forefront of the country.。
The smoothness of asphalt pavement is related to the driving experience of drivers and passengers.，It is also one of the key factors for the external evaluation of the construction quality of the project.，Reflect the management level and technical strength of the construction unit。How to Improve the Flatness of Asphalt Pavement，Let the people enjoy a higher quality of highway driving experience？Guangxi Road Construction Group has been exploring and researching in this field for many years.，Remarkable results have been achieved.。
Asphalt pavement construction is the key project of expressway pavement construction.，The process is complex，Strict quality control，High technical content requirements。“Uniform speed is required for asphalt paving、Continuous，It is necessary to ensure that all key construction links are connected.，Benefit from management、The duration is required。”Talking about Construction Experience of Asphalt Pavement Smoothn，Expressway from Daxin to Pingxiang via Longzhou№Huang Pengcheng, the executive deputy manager of Section 3 project, explained clearly and logically.。He told reporters，Guangxi Road Construction Group has formed a mature construction management.、Equipment management、Material control、Test and detection linkage system，The management team continuously absorbs the management experience of road and bridge construction under various topographic and geological conditions.，Relying on a strong technical team，Summarize the edge paving、Edge detection、Side feedback、The edge is finely tuned“Four sides”Quality Control Mode of Asphalt Pavement，Build“Black pavement”Construction management brand，Provide management guarantee for improving the quality of asphalt pavement。

It is understood that，The efficiency of asphalt paving is directly related to the quality and progress of highway construction.，In addition to the efficient coordination between processes，New technology、The support of new technology is also indispensable.。Highway from Hezhou to Bama(Section from Laibin to Duan)№Bid section 1 is under construction，Guangxi Road Construction Group has successfully explored and taken the lead in promoting its application in Guangxi.“Double bunk”Construction technology of cement stabilized base of pavement，Namely, the spreading material is conveyed transversely by the conveying distributor.，After the first layer is formed by water-stabilized paving and rolling，Immediately spread and roll the second layer until it is formed，Covering and curing shall be carried out after continuous paving of two layers.，That is“Double bunk、Rolling in layers、One-time molding”。With the support of new technology，The project construction efficiency has been greatly improved.，Shorten the construction period by nearly half，The working surface for the next stage of asphalt pavement paving was opened before the rainy season.。Compared with the traditional process,，The construction technology ensures water stability.、Cohesion and integrity of the next two layers，The strength of the structural layer is greatly improved.、Stiffness and stability，The service life of the pavement is prolonged.；The process of spreading cement paste between the traditional double-layer single-layer paving is reduced.，Reduce the transition times of paving and rolling equipment，The overall work efficiency of the construction is greatly improved，And that cost is also reduce.。After acceptance，The standard deviation of the pavement smoothness of this project is only 0..378 mm。
Asphalt paving
Improvement of Asphalt Pavement Paving Quality，It is a concentrated display of various scientific research achievements.。Over the years，Guangxi Road Construction Group and peer enterprises inside and outside the region、Scientific research institutions、Scientific research cooperation between universities and other institutions，Promote the continuous improvement of asphalt pavement quality in Guangxi。Among，Cooperation with the Scientific Research Institute of the Ministry of Transport and other units《Research on Development and Application Technology of Warm Mix Asphalt Pavement Modifier》The achievement won the second prize for scientific and technological progress of China Highway Society.，《Innovation and Application of Asphalt Pavement Quality Assurance Technology in Hot Summer and Winter Temperature Zone》Won the third prize of Guangxi Science and Technology Progress。
0.01 mm accuracy，It's by 100%In exchange for effort and sweat.。From 0.4 mm，To 0.389 mm、0.366 mm，And then to 0.354 mm……Guangxi Road Construction Group is constantly calling for asphalt pavement flatness data one by one.“Black pavement”Word of mouth，Contribute wisdom and strength to highway construction。
