Influence of material modification optimization of superviscous abrasion layer on the performance of asphalt pavement
The slip and wear resistance of asphalt pavement plays a crucial role in road longevity,driving safety and driving comfort.for the purpose of improving the performance of asphalt pavement through superviscous abra-sion layer,matrix asphalt,emulsifier,hydrochloric acid,stabilizer and viscosity reducer were used as the basic ma-terials of superviscous abrasion layer,and styrene-butadiene-styrene terpolymer(SBS)modifier was added to pre-pare bonding materials,and ore,cement,fiber,emulsified asphalt and water were prepared according to the ratio of 100∶1.0∶0.2∶11.0∶6.0.The adhesive material was evenly spread on the asphalt pavement and the super-adhesive abrasion layer mixture was paved to test its optimal performance.The effect test showed that the minimum permea-bility coefficient of the applied material was kept between 400～450 mL/min,the flatness detection was kept below 1.0mm,the rut deformation did not exceed 3.0%,the compressive strength was between 27～28 MPa,the highest damage rate did not exceed 5%,and the wear resistance and anti-slip effect were good,with strong effects of water-proof fog and noise reduction,and the impact of road operation was small.
