AC-16型沥青混合料工程设计级配范围研究

ENGINEERING DESIGN GRADING ENVELOPE OF AC-16 BITUMINOUS MIXTURE

新《公路沥青路面施工技术规范》中AC-16沥青混合料的矿料级配范围定的太宽,需结合工程情况提出工程设计级配范围。在提出武汉地区沥青路面使用性能气候分区的基础上,对4种AC-16级配形成的沥青混合料的高温稳定性、水稳定性等使用性能进行了研究,提出适用于武汉地区高等级公路沥青路面的AC-16型沥青混合料的工程设计级配范围,并给出其设计级配的选择建议。

In the new《Technical Specifications for envelope of AC - 16 bituminous mixture is too big . Construction of Highway Asphalt Pavements》, the grading Combining with the fact engineering , We should raise the engineering design grading envelope. On the base of raising the use performance climate subarea of asphalt pavement in Wuhan region, this paper studies the use performance of four AC -16 bituminous mixture ,etc. high temperature stability and water stability. This paper also raises the engineering design grading envelope of AC - 16 bituminous mixture which is applicable to the asphalt pavement of high - grade highway in Wuhan region , and raises the advice of choosing design grading of AC - 16 bituminous mixture.
