“…The objective in designing the mortar mix in the present research was to reproduce mortar mix proportions as they exist in a typical binder course mix [35][36][37][38]. The binder course mortar mix proportions were calculated using only constitutive materials passing through a 6.3mm sieve size, namely sand and Crushed Rock Fines (CRF).…”

“…The total size of the overlaid area was approximately 120m 2 ; this required about 15 tonnes of mix to cover. Due to restrictive site access and subgrade conditions, the material had to be laid by hand.…”

“…Recent investigations have focussed on the mechanical performance of standard bituminous mixtures using uniaxial fatigue tests [1][2][3] and fatigue wheel tracking laboratory tests [4]. The present paper describes a full scale accelerated loading performance test on a 20mm Dense Base Coarse Macadam [6] which overlaid a peat based forest access roads [5].…”

The in-service behaviour of a standard Irish Dense Base Coarse Macadam mixture (DBC) was evaluated by using the material to overlay a road section, which was based upon a weak pavement structure. The response of the layer under a fully laden dual axle truck was examined using a series of pressure cells and asphalt strain gauges that were embedded in the test section. The section was traversed repeatedly until a network of fatigue cracks was observed on the road surface. The transverse horizontal tensile strain was found to be the most critical parameter in initiating pavement damage. INTRODUCTIONFull scale test facilities offer particular advantages over simulated laboratory programmes: the effects of size, construction, substructure, boundary and loading conditions correspond more closely to the actual on-site conditions than can be simulated directly with model experiments. However, it is seldom possible to control temperature and moisture when using such facilities and consequently there are always inherent disparities when attempting to relate laboratory and in-situ test data.

“…In contrast, other studies have shown that the laboratory roller compactor best emulates the mechanical performance of field cores (Sousa et al 1991). More recent studies comparing the results of the indirect stiffness testing on specimens manufactured from laboratory compaction methods have found that steel roller compacted specimens were of comparable stiffness to the site cores, although lower stiffness values were determined for site compacted specimens (Hartman et al 2001, Airey et al 2006. However, these studies have not focused on the roller compaction factors that affect the laboratory densification, and subsequently their impact on asphalt mix mechanical performance in relation with field performance.…”

This study aims to investigate the relationship between different roller compaction modes and resulting mechanical performance. In order to accomplish these objectives, a trial asphalt pavement section was observed and monitored both during the paving and compaction processes. Asphalt mix was sampled from the paver to be used later in laboratory and evaluate the differences between compaction in-field and laboratory. Asphalt concrete mixes were prepared and compacted in the laboratory using a steel roller compactor, with varying factors that influence compaction in terms of compaction modes (static, vibratory and a combination of both), as well as effort and temperatures in order to attempt to simulate field compaction conditions. The identification of a harmonised compaction procedure for specimen fabrication able to produce mixtures with stiffness properties resembling field compacted mixtures was also investigated based on the performancebased test results.
