In place, sustainable rehabilitation of existing deteriorated concrete highways through rubblization is considered to be a green and economical alternative to other options involving total reconstruction, etc. There is currently no standardised method of backcalculating the rubblized pavement layer moduli from pavement non-destructive test data through inverse analysis. This paper explores the ...

BACKGROUND In this study, concrete application as a substrate for TiO2 nano powder immobilization in heterogeneous photocatalytic process was evaluated. TiO2 immobilization on the pervious concrete surface was done by different procedures containing slurry method (SM), cement mixed method (CMM) and different concrete sealer formulations. Irradiation of TiO2 was prepared by UV-A and UV-C lamps. ...

This paper evaluates the effect of mix design parameters on mechanical, hydraulic, and durability properties pervious geopolymer concrete (PGC) made with a 3:1 blend granulated blast furnace slag (GBFS) fly ash (FA). A total nine PGC mixtures were designed using Taguchi method, considering four factors, each at three levels, namely, binder content, dune sand addition, alkaline-activator solutio...

In the present investigation, an experimental study was conducted to evaluate the thermal stresses in rigid pavement. In pavements design, temperature differential is having dominant role across the depth at critical locations. Seasonal climate changes influences the characteristic of pavement track. The study influences the behavior of the pavement slab in a nonlinear manner. The critical stre...

The Long-Term Pavement Performance (LTPP) database contains surface profile data for numerous pavements that are used mainly for computing International Roughness Index (IRI).(2) In order to obtain more information from these surface profiles, a Hilbert-Huang Transform (HHT) based surface profile algorithm was developed to analyze LTPP field road profile data in order to extract smoothed, consi...
