Table 3 Test method of cooling effect [66, 71,72,73,74]
From: Review of regulation techniques of asphalt pavement high temperature for climate change adaptation
Test methods | Temperature measurement position | Disadvantage | Advantage | |
|---|---|---|---|---|
Determination of thermal parameters | Thermal conductivity | Entirety | Cannot directly explain the cooling effect | Rapid; Simple; Reproducible |
Specific heat capacity | ||||
Indoor irradiation test | Upper and lower surfaces and representative positions | Difference from real road light thermal environment | Reproducible | |
Outdoor irradiation test | Upper and lower surfaces and representative positions | Non-repeatable; Affected by weather | Closest to reality | |
Finite element simulation | Optional position | Low credibility | The temperature change at any time at any position can be measured. | |
