Flexible pavements are one of the vital gears of transportation systems [1] that sustain socio-economic growth for a nation [2]. However, their construction and preservation require large capital investment [3]. Thus, ensuring sustainable flexible pavements [4] has become a primary focus of flexible pavement management systems and highway agen …
Flexible pavement refers to a type of road construction that comprises multiple layers of materials designed to provide strength, durability, and flexibility. This type of pavement is commonly used for highways, roads, parking lots, and other transportation infrastructure projects. Unlike rigid pavement, which uses concrete as the primary ...
Pavement Manual: Flexible Pavement Construction. 1.2 Introduction. This chapter provides a general overview of the equipment and procedures involved in the construction flexible pavements. The equipment includes hot-mix plant operations, trucks, placement equipment, and compaction equipment.
We drive on roads and highways and park in asphalt paved parking lots every day, but have we ever taken a moment to think about what manpower and equipment is necessary to …
Sahaa et al. ( 2014) investigated the performance of flexible pavement for varying climatic conditions using MEPDG. It was observed that total pavement rutting, international roughness index (IRI) and asphalt concrete are amongst most sensitive parameters to climatic changes. Orobioa and Zaniewskib ( 2013) used a software tool for …

Flexible pavements are subjected to loading stresses and resulting strains dependent on the existing environmental conditions. Distresses in the form of rutting and cracking occur in pavements due to progressive damage accumulation caused by repeated traffic-induced stresses/strains. For the accurate design of pavements, a knowledge of …
Flexible pavements constitute a pivotal element of our transportation infrastructure, seamlessly facilitating the movement of vehicles while enduring the challenges posed by …
We drive on roads and highways and park in asphalt paved parking lots every day, but have we ever taken a moment to think about what manpower and equipment is necessary to construct these large areas of pavement?
Design of flexible pavements is not straightforward when reinforcement materials such as geogrid, geocell, and other types of geosynthetic materials are used in pavement construction.
In this paper, a methodology was proposed for structural evaluation and overlay design determination on thin flexible pavements (less than 100 mm). The use of the lightweight deflectometer is the nondestructive technique for structural evaluation of thin bound and unbound pavement layers.
1. Hot-mix plant is used for a) Cement concrete pavement Construction. b) Bituminous pavement construction. c) Water bound macadam construction.
Construction quality is crucial to the long-term pavement performance. Construction factors such as surface preparation, placement, joint construction and compaction/consolidation have an overwhelming effect on pavement performance, which cannot be ignored or compensated for in mix or structural design. Other construction …

Heavy machines are required in different large projects to make the job safer and easier. Road construction is a specialized area of construction that is highly technical, requiring various specialized equipment. Whether it's building a new road, or rehabilitating an old road, using the right machine is important. Today, we'll dive into this …

Sixteen sections—four construction platforms and 12 flexible pavements—were evaluated with the Accelerated Transportation Loading Assembly (ATLAS) at ICT for rutting and fatigue performance.
The use of fly ash in construction has been on the rise, yet its application in pavement construction remains relatively underexplored.
The findings indicate that flexible pavement is more cost-effective than rigid pavement. Among flexible pavement design methods (AASHTO and AI), AI emerges as the most cost-effective. For rigid pavement design methods (AASHTO and PCA), PCA proves to be the most cost-effective, while rigid pavement stands out as the most expensive option.
Airport runways and taxiways are commonly comprised of a flexible pavement with an asphalt surface. Marshall-designed asphalt with sawn grooves is the most frequent airport asphalt surface material.
Perpetual Pavement: Way Forward from Design to Quality Construction. Atasi Das, Assistant Vice President, G R Infraprojects, explains the concept of the Perpetual Pavement in India's expressway constructions and its practical implementation with due consideration of layers, materials, and thicknesses that are unique and relevant to Indian ...
Pavements are the major application in which fly ash can be effectively used and result in significant savings in land-filling costs. Relying on Class C fly ash in the presence of lime, Bergeson and Barnes 1998 developed design guidelines for determining the structural layer coefficient for the base layer of flexible pavement.
DBM (Dense Bituminous Macadam) is a part of flexible pavement and the work shall consist of construction of single or multiple layers on wmm or sub base. Mix Design of DBM for Highway Project
