Author:Komba, Julius J; Mataka, M; Malisa, JT; Walubita, LF; Maina, JWDate:Jun 2018Traffic loading is one of key inputs for new and rehabilitation designs of pavement. Heavy vehicles cause the most structural damage to pavements; hence, as part of the pavement design process, heavy vehicle volume, and axle load surveys are ...Read more
Author:Steyn, WJvdM; Denneman, E; Mahlangu, SDate:Jul 2008In this paper the focus is on the comparison between the permanent deformation behaviour of the standard HMA mix and one rut resistant HMA mix of which the grading differs from that of the standard HMA mix. The permanent deformation has been ...Read more
Author:Jooste, FJ; Kekwick, SV; Sadzik, ES; Rohde, GTDate:Aug 1997The aim of this study was to investigate the following:how accelerated pavement testing predictions compare with actual road behaviour and performance the relative influences of load and environmental factors on pavement deterioration and how ...Read more
Author:Walubita, LF; Ling, M; Fuentes, L; Komba, Julius J; Mabrouk, GMDate:Sep 2022Asphalt binder is one of the key constitutive components of hot-mix asphalt (HMA) that considerably affects its rutting performance. In particular, the high-temperature rheological properties measured from the multiple stress creep and recovery ...Read more
Author:Walubita, LF; Fuentes, L; Prakoso, A; Pianeta, LM; Komba, Julius J; Naik, BDate:Mar 2020Rutting is one of the common distresses occurring in hot-mix asphalt (HMA) pavements that can be mitigated through adequate laboratory testing during the HMA mix-design screening stage. The Hamburg Wheel Tracking Tester (HWTT) is one of the ...Read more
Author:Maina, JW; De Beer, Morris; Matsui, KDate:Aug 2007In this study, the effect of layer interface slip rate on the critical responses such as (primary) tensile strains as well as strain distortion energies for a flexible runway pavement structure is examined based on strain energy of distortion. ...Read more
Author:Ampadu, SIK; Lawer, AK; Anochie-Boateng, JosephDate:Aug 2015Many newly constructed asphaltic pavements in Ghana have suffered premature failures shortly after opening to traffic. In all cases, available records from the road agencies appeared to show that the roads were constructed in accordance with ...Read more
Author:Anochie-Boateng, Joseph; Mataka, MO; Malisa, JT; Komba, Julius JDate:Nov 2015Tanzania is faced with challenges of premature failures in roads and highways. Some asphalt pavements fail prematurely in less than five years of their expected 20 years design life cycle. These failures have been identified as mostly permanent ...Read more
Author:Komba, Julius J; Anochie-Boateng, Joseph; O'Connell, Johannes S; Verhaeghe, Benoit MJADate:Sep 2016Enrobé à Module Élevé (EME) technology, a High Modulus Asphalt (HiMA), was originally developed in France. The technology is primarily suitable for construction of heavily trafficked routes, airports and container terminals. The key performance ...Read more
Author:Anochie-Boateng, Joseph; Tutumluer, E; Carpenter, SHDate:2008Oil sand, or tar sand, is a generic name given to bituminous sand deposits that are rich in bitumen or asphalt content to the extent that oil can be extracted from these deposits. The typical 8% to 15% presence of bitumen in the soil composition ...Read more
