Assessment of traffic data for road rehabilitation design: A case study of the Korogwe-Mombo road section in Tanzania

Author: Komba, Julius J ; Mataka, M ; Malisa, JT ; Walubita, LF ; Maina, JW Date: Jun 2018 Traffic 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
Comparative assessment of the interlayer shear-bond strength ofgeogrid reinforcements in hot-mix asphalt

Author: Walubita, LF ; Nyamuhokya, TP ; Komba, Julius J ; Tanvir, HA ; Souliman, MI ; Naik, B Date: Dec 2018 With the increasing use of geogrid reinforcements to mitigate reflective cracking in hot-mix asphalt (HMA) overlays, interlayer (interface) bonding has become an even more critical aspect of HMA placement/construction to mitigate delamination ...

Correlating the asphalt-binder high-temperature properties (DSR) to HMA permanent deformation (RLPD) and field rutting: A laboratory-field study

Author: Walubita, LF ; Mahmoud, E ; Fuentes, L ; Prakoso, A ; Lee, SI ; Souliman, M ; Komba, Julius J Date: Nov 2020 Asphalt-binders are part of the key material constituents affecting the performance of hot-mix asphalt (HMA), and ultimately, the field performance of flexible pavement structures. Quite often, it is desired/useful to predict the HMA permanent ... Read more
Correlating the asphalt-binder MSCR test results to the HMA HWTT and field rutting performance

Author: Walubita, LF ; Ling, M ; Fuentes, L ; Komba, Julius J ; Mabrouk, GM Date: Sep 2022 Asphalt 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
Correlating the HWTT laboratory test data to field rutting performance of in-service highway sections

Author: Walubita, LF ; Fuentes, L ; Prakoso, A ; Pianeta, LM ; Komba, Julius J ; Naik, B Date: Mar 2020 Rutting 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
Geogrid reinforcement in hot-mix asphalt: Interlayer shear bond strength assessment

Author: Walubita, LF ; Hu, X ; Nyamuhokya, TP ; Komba, Julius J ; Souliman, MI Date: Jan 2018 With the increasing use of geogrid reinforcements to mitigate reflective cracking in hot-mix asphalt (HMA) overlays, interlayer (interface) bonding becomes an even more critical aspect of HMA placement/construction to mitigate delamination ...

The Hamburg Rutting Test (HWTT) alternative data analysis methods and HMA screening criteria

Author: Walubita, LF ; Faruk, ANM ; Zhang, J ; Komba, Julius J ; Alrashydah, EI ; Simate, GS Date: Apr 2019 The Hamburg Wheel Tracking Test (HWTT) is a widely used routine laboratory test for identifying and screening hot-mix asphalt (HMA) mixes that are prone to rutting. The standard HMA pass-fail screening criterion under the current HWTT protocol ... Read more
Mechanistic-empirical compatible traffic data generation: Portable WIM versus cluster analysis

Author: Walubita, LF ; Fuentes, F ; Faruk, NM ; Komba, Julius J ; Naik, B ; Prakoso, A Date: May 2020 Axle load distribution factors (ALDFs) are used as one of the primary traffic data inputs for mechanistic-empirical (ME) pavement design methods for predicting the impact of varying traffic loads on pavement performance with a higher degree ...

Pavement serviceability evaluation using whole body vibration techniques: a case study for urban roads

Author: Fuentes, L ; Camargo, R ; Martinez-Arguelles, G ; Komba, Julius J ; Naik, B ; Walubita, LF Date: Sep 2019 Quantification of the pavement serviceability is most often based on the international roughness index (IRI). However, in urban environments it can become challenging to drive at 80 km/h as vehicle operating speeds are much lower, among other ... Read more
Portable WIM systems: Comparison of sensor installation methods for site-specific traffic data measurements

Author: Walubita, LF ; Mahmoud, E ; Fuentes, L ; Komba, Julius J ; Teshale, EZ Date: May 2021 As an alternative to costly permanent weigh-in-motion (WIM) stations that are mostly limited to major interstate highways, portable WIM systems are often used as a substitute or supplement to routinely collect site-specific traffic data (both ... Read more
Traffic data characterization for road rehabilitation: A case study of the Korogwe-Mombo road section in Tanzania

Author: Komba, Julius J ; Mataka, M ; Malisa, JT ; Walubita, LF ; Maina, JW Date: Jul 2018 Traffic loading is one of the key inputs for the structural design of pavements. For pavement design purposes, heavy vehicles are mostly used for the estimation of the traffic load spectra, as they cause the most structural damage to pavements. ... Read more
Use of grid reinforcement in HMA overlays - A Texas field case study of Highway US59 in Atlanta District

Author: Walubita, LF ; Mahmoud, E ; Lee, SI ; Carrasco, G ; Komba, Julius J ; Fuentes, L ; Nyamuhokya, TP Date: Jul 2019 One of the common methods to mitigate reflective cracking, in existing cracked pavements, is the use of interlayer grid reinforcements in hot-mix asphalt (HMA) overlay construction during maintenance and/or rehabilitation projects. As a means ... Read more
