Recycling thickness test method for asphalt pavement in hot in-place recycling project
The invention discloses a recycling thickness test method for an asphalt pavement in a hot in-place recycling project. The method comprises the following steps: step 1, ordinary Portland cement is uniformly spread on a milled and planed pavement in a hot in-place recycling construction process of the asphalt pavement; step 2, after paving and rolling in a cement spreading position and the pavement temperature is reduced to 50 DEG C, a pavement core drilling rig is used for core drilling at a cement spreading center point; step 3, the diameter d of a core sample is measured; step 4, the core sample is placed in a hydrostatic balance, the weight m1 of the core sample in water is weighed, and the saturated surface dry mass m2 of the core sample is measured after the core sample is taken out; and step 5, the thickness of a recycling layer is calculated. The recycling thickness of the asphalt pavement in the hot in-place recycling project can be described effectively and accurately with the test method.
