Title:
PAVEMENT PART OFFERING EXCELLENT GEOTHERMY TRANSMISSION FUNCTION, HIGH-FUNCTION SUBGRADE MATERIAL AND ROADBED MATERIAL, AND PAVEMENT PART CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2016216922
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pavement part offering excellent geothermy transmission function.SOLUTION: A subgrade 6 is formed by compacting a high-function subgrade material made by mixing decay-proof konjak of particle sizes between a rice grain and a granule into a subgrade aggregate. A roadbed 7 is formed on the subgrade 6, by compacting a high-function roadbed material made by mixing the decay-proof konjak into a roadbed aggregate. An upper pavement layer 9 is formed on the roadbed 7. The decay-proof konjak is strongly alkali konjak, and has decay-proof, insect-proof and mildew resisting properties. The decay-proof konjak has a thermal conductivity of about 0.79 to 0.84 W/(m*k), and is filled in an inner gap part between aggregates formed inside the subgrade 6 and the roadbed 7. The configuration enables a pavement part to be formed that offers an excellent geothermy transmission function.SELECTED DRAWING: Figure 1
