Evaluating life cycle cost and performance comparison between cold in place recycling and reconstruction method

Many commentators pointed out that large amount of money had been spent in maintaining and sustaining the road pavement every year in Malaysia. The rapid road deterioration and eventual failure from both climatic and vehicle loads impacts have significantly incurred the total cost of road maintenan...
