Abstract
The present invention provides a method of calculating the dosage of phase change coarse aggregate, which comprises the steps of setting a regulatory temperature difference of a thermoregulating cement-stabilized layer, the regulatory temperature difference being the difference between the peak temperature of the thermoregulating cement-stabilized layer and the peak temperature of a conventional cement-stabilized layer, wherein the thermoregulating cement-stabilized layer is mixed with a phase change coarse aggregate, while the conventional cement-stabilized layer is not mixed with a phase change coarse aggregate; calculating a regulatory heat based on the regulatory temperature difference, wherein when a temperature change of the conventional cement-stabilized layer is the regulatory temperature difference, a heat change of the conventional cement-stabilized layer is the regulatory heat; and calculating a volume occupied by the phase change coarse aggregate in the thermoregulating cement-stabilized layer based on the regulatory heat.
