Case study of longitudinal thermal cracking related to asphalt concrete pavement construction

In the construction of asphalt mixture pavement, there are many paving construction procedures, high requirements for machinery and personnel, unreasonable technology and so on. In this paper, the millimeter-scale 3D automatic paving control technology of asphalt mixture pavement is studied with an engineering example. From the analysis of the test results in the later stage of construction, it can be seen that the technology has achieved the goal of high precision paving, and the successful application of the technology provides valuable reference experience for similar asphalt concrete pavement construction in the future.

Asphalt Concrete Pavement

Focusing on the severity of asphalt concrete pavement crack, the optimization analyzing finite element model(FEM) of typical asphalt overlay pavement was developed to address reflective cracking, in which the analysis of traffic-loading response were concentrated on the stress-intensive areas close to the joints or cracks. The FE sensitive analysis, evaluating the influence of pavement construction parameters, including modulus and thickness of pavement courses, is useful to establish comprehensive model of overlay pavement construction.

Asphalt Concrete Pavement

The high temperature of asphalt concrete pavement decreases its bearing capacity, thus leading to serious rutting. In this paper, a coated thermal resistance/heat reflection pavement construction technology with a coating of 2-3mm on the asphalt pavement is mainly introduced, which can reflect and prevent sunshine and reduce the surface temperature of asphalt pavement for the purpose of preventing rutting. In addition, the coated thermal resistance/heat reflection paving method is introduced, which is of certain reference to the promotion and application of coated thermal resistance/heat reflection pavement.
