Georadaro taikymas asfalto dangų įrengimo kokybei įvertinti / Evaluation of the use of GPR in quality control of asphalt pavement layers

Abstract

The optimum density and air-voids content of asphalt pavement layers are among the main indicators of the durability of asphalt road pavement. The asphalt pavement with insufficient density is less resistant to traffic loading and the damaging effects caused by water. Air-voids ensure the durability of asphalt pavement and the accumulation of free bitumen during a period of hot weather. At present, the main ways to control the quality of compaction and the content of air-voids is to drill core specimens and test them in the laboratory. This method is expensive, it damages the road surface, and the quality of asphalt pavement is verified only at several points. With the rapid development of new technologies, it is necessary to evaluate and to apply innovative non-destructive methods, allowing us to determine the qualitative characteristics of asphalt pavement across the entire length of the road without causing the damage to the road surface and at lower costs. This article describes the use of Ground Penetrating Radar to determine asphalt pavement density and air-voids content provides an overview of global practices and feasibility analysis on the application of Ground Penetrating Radar on the roads of Lithuanian.

Asfalto dangos sluoksnių optimalus tankis ir oro tuštymių kiekis yra vieni iš pagrindinių dangos ilgaamžiškumo rodiklių. Nepakankamo tankio danga yra mažiau atspari automobilių eismo apkrovoms ir žalingam vandens poveikiui. Oro tuštymės užtikrina dangos ilgaamžiškumą ir laisvojo bitumo akumuliavimą karštuoju metų laikotarpiu. Šiuo metu pagrindinis būdas kontroliuoti sutankinimą ir oro tuštymių kiekį yra gręžti kernus ir juos bandyti laboratorijoje. Šis metodas yra brangus, gadinama kelio danga ir asfalto dangos kokybė patikrinama tik keliuose taškuose. Sparčiai vystantis technologijoms būtina įvertinti ir taikyti inovatyvius neardančiuosius metodus, leidžiančius kokybinius asfalto dangos rodiklius nustatyti neardant dangos, išilgai viso kelio ir mažesnėmis sąnaudomis. Šiame straipsnyje pateikta georadaro (angl. Ground Penetrating Radar) taikymo asfalto dangai sutankinti ir oro tuštymių kiekiui nustatyti pasaulinės praktikos apžvalga ir panaudojimo Lietuvos automobilių keliuose galimybių analizė.
