Spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. Concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. Therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...

In today's competitive market, technology transfer is an important problem for firms, organizations and governments. Therefore, making right decisions on selecting a suitable technology and designing an appropriate process to transfer it may have significant influence on the performance of organizations. In this paper, we present a new method to obtain a suitable technology transfer strategy fo...

Pavement maintenance and rehabilitation have been neglected in Nigeria for a very long time and has resulted to maintenance backlog. Design agencies in Nigeria still use California Bearing Ratio (CBR), even though the method is outdated. An introduction of Dynamic Cone Penetration Test (DCPT) was pertinent, even though the method is relatively old in some developed countries, it has not gain mu...

Using recycled concrete aggregate (RCA) as base/subbase for road construction is alternative way to manage construction waste and reduces the need for virgin aggregates. This paper discusses the long-term performance of concrete pavements on RCA granular layer in comparison to concrete pavements on virgin aggregate granular layer. 18 representative RCA pavement sections across Iowa were primary...

This research project developed self-sensing carbon-nanotube (CNT)/cement composites. The piezoresitive property of carbon nanotubes enables the composite to detect the stress/stain inside the pavement. Meanwhile, CNTs can also work as the reinforcement elements to improve the strength and toughness of the concrete pavement. Experimental results show that the electrical resistance of the compos...

A. Panas and J.-P. Pantouvakis · Multi-attribute regression analysis for concrete pavement... · pp 289-295 INTRODUCTION Concrete pavement layering is a process that requires the combination of laborand machine-intensive operations. As such, the implications and the interactions of the affecting factors pose a significant research interest, given that published productivity or cost data are scar...

Pavement breaking generates a high level of ground vibration that is potentially damaging to nearby buildings and infrastructures. In this paper, a numerical model for the estimation of the impact load due the blow of a falling-weight pavement breaker is first developed. The estimated impact load is in good agreement with the experimental result. Next, the fracturing of the concrete road is inv...

Since it is a design criteria for road drainage and sewer systems, the infiltration performance of permeable concrete block pavement (CBP) is of important significance during the service life of a road construction. Due to the entrainment of mineral and organic fines into the pores of porous concrete blocks or into the aggregates used in joints or openings, the irreversible reduction of water p...

Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...
