Abstract


Semi-rigid base asphalt pavement reflection cracking problem so far has not been effectively resolved . The study shows that reflection cracks , With the rapid growth of traffic and increasing tire pressure , however , has become thick asphalt layer asphalt pavement rutting problems can be alleviated by increasing the thickness of the asphalt layer . Domestic and international studies have shown that the large size asphalt mixture (LSAM) has good resistance to reflective cracking and rutting resistance ability , can effectively solve the above problem . LSAM as a skeleton dense asphalt mix with friction and embedded squeeze force , skeleton and stability . Accordingly, this article using the LSAM the target volume of the test design method based on uniform design mix design. Performance test results show that the : LSAM anti- rutting much larger than ordinary asphalt mixture ; of LSAM the embedded crowded dense structure has good resistance to water damage ; The LSAM the average tensile strength than semi-rigid base materials increased by 52.7% . Calculated by ANSYS , the results show that the large stone asphalt mixes the grassroots than traditional asphalt mix grassroots mitigation of reflective cracking . LSAM coarse aggregate nominal particle size , and thus the thermal conductivity , temperature shrinkage coefficient , low resilient modulus . These features help to reduce the temperature gradient in the pavement between the various layers , thereby reducing the thermal stress, LSAM have enough flexibility to fully absorb the strain energy of the cracks , which has a strong crack control ability . Combined with Shanghai-Chengdu Expressway should be long segment the test road paving LSAM grassroots instance of the LSAM the construction technology and construction performance . Construction quality testing results show that the the LSAM Base Asphalt Pavement overall strength enough ; the LSAM grassroots better compaction performance and structural compactness . Through five months of observation , reflective cracking test road in good condition . The Test Road resist rutting deformation capacity pending further verify the observation .
