Abstract
Growth of economy and population density, open space is being converted to roads or other infrastructures such as buildings or parking lots reducing green space. This paper demonstrates a new type of green pavement designed to replace flexible and rigid pavements which are water impermeable and have a short design life. This type of green pavement helps reduce runoff problems in urban areas. StormPav GP is an innovative Industrialised Building System (IBS) Green Pavement which has been shown to have structural, environmental and economic advantages. However, its susceptibility to distress has yet to be analyzed. This study addresses this gap by analyzing the mechanistic properties and evaluating distress of StormPav GP as compared to flexible and rigid pavements. WinJULEA, KenPave and Circly 6.0 were used for this analysis which also investigated the effects of different tire pressures on deflections. StormPav GP was found to have lower deflection due to a tandem axle dual wheel load on any pavement surface and provided a more uniform settlement with higher elastic modulus and shear modulus than flexible and rigid pavement.
Highlights
As more of the surface area in urban and rural areas becomes covered by roads and buildings green areas are reduced
This research has compared the performance of the StormPav GP with both rigid and flexible pavement, can be concluded as follows, 1
The deflection of the surface pavement is influenced by the tire pressure and contact radius
Summary
As more of the surface area in urban and rural areas becomes covered by roads and buildings green areas are reduced. This lack of filtering vegetation and absorbent soil surface disrupts absorption and increases runoff rates. This absence of vegetation is a considerable challenge for regions with heavy rainfall, such as in Indonesia. Software modelling is used to investigate surface distress on StormPav GP in response to different tire pressure and the allowable load repetition. It is assumed that StormPav GP has many of the same characteristics as rigid pavement because both produce monolithic solutions in response to the applied load
