Problems solved by technology

It takes a period of time for the heating machine to heat the road surface to allow the heat to conduct to the lower layer of the road surface. Continuous heating of the road surface will cause serious aging or even burning of the asphalt on the road surface, and the lower layer cannot reach the target temperature, so a certain distance is required between the two heaters
After heating in this interval, the surface of the road is exposed to the air, which will lose a lot of heat and reduce the thermal efficiency, which not only causes waste of energy, but also affects the construction quality.
There are no relevant supporting facilities to solve this problem in the existing hot-in-place regeneration equipment

Abstract

The invention discloses a road pavement heat insulation plate for a local heat regeneration unit. The road pavement heat insulation plate comprises a first heat insulation plate, a second heat insulation plate, a third heat insulation plate and a fourth heat insulation plate which are sequentially connected, wherein the first heat insulation plate and the second heat insulation plate form a firstheat insulation unit; the third heat insulation plate and the fourth heat insulation plate form a second heat insulation unit; the first heat insulation plate and the third heat insulation plate are respectively connected with a steel strand line, and the steel strand line penetrates through a pulley block and then is wound on an electric winch; the electric winch is used for retracting and deploying the steel strand line via the pulley block, the first heat insulation unit and the second heat insulation unit are folded or unfolded to the horizontal state, and the heat of the heated asphalt road pavement is insulated. The road pavement heat insulation plate has the advantages that the problem of heat loss of the original road pavement at the heating gap of the heating machine is effectively solved; by covering the heat insulation plate, the coverage heat insulation is performed, so as to reduce the carrying-away of the heat due to air flowing; and the heat efficiency is improved, and the purposes of energy saving and emission reduction are further realized.

Description

technical field [0001] The invention relates to the field of hot-in-place recycling equipment for asphalt pavement, in particular to a hot-in-place regeneration unit for asphalt pavement, and more specifically to a road insulation board for the hot-in-place regeneration unit. Background technique [0002] In the construction of hot-in-place regeneration of asphalt pavement, it is necessary to heat the original pavement to raise the temperature of the original pavement to a temperature suitable for construction, and then carry out milling and mixing processes. Raising the pavement temperature in hot-in-place regeneration construction is an important factor to ensure the construction quality in the whole construction process. It takes a period of time for the heating machine to heat the road surface to allow the heat to conduct to the lower layer of the road surface. Continuous heating of the road surface will cause serious aging or even burning of the road asphalt, and the lo...
