Cement stabilized macadam base structure and construction method
According to the cement stabilized macadam base layer structure and the construction method, the base layer structure is composed of a stress compensation type upper base layer, a cement paste connecting layer and a stress compensation type lower base layer, and the upper base layer is composed of an upper stress compensation seam and upper base layer cement stabilized macadam; the upper stress compensation seam is formed by pouring upper base layer high-expansion concrete into the pre-cutting seam of the stress compensation type upper base layer. The construction method of the cement stabilized macadam base structure comprises the following steps: 1) constructing the stress compensation type lower base; (2) constructing a lower stress compensation seam; (3) constructing a cement paste connecting layer; (4) a stress compensation type upper base layer is constructed; (5) the upper stress compensation seam is constructed; according to the cement stabilized macadam base structure and the construction method, the influence of dry shrinkage and temperature shrinkage on the cement stabilized macadam base can be reduced or eliminated, the time of transverse cracks of the cement stabilized macadam base due to fatigue is prolonged, the strength of the cement stabilized macadam base can be greatly improved, and the service life of an asphalt pavement is prolonged.
