the impact of one two and three component hydraulic road binder on the properties of the Hydraulically Bound Mixture
Procedia Engineering, 2015Co-Authors: Przemyslaw Buczynski, Maciej LechAbstract:Abstract The paper presents the results of tests on road base used in the construction and maintenance of roads stabilised with hydraulic binders. Seven hydraulic binder mixes were prepared under laboratory conditions by mixing three basic components: Portland cement CEM I 32.5 R, fluidized bed combustion ash (PF) and cement kiln dust (CKD). The proportions of the binder components were established in accordance with the experimental design. The percentage share of the hydraulic road binder in the Bound mix was 6%. Two types of natural aggregates were used for the base. The percentage shares of the individual components in the mix were designed using the Proctor method. For pastes, made from binders, basic mechanical properties were determined. To assess the effect of binders on the properties of the base stabilised with Hydraulically Bound Mixtures tests were conducted to measure the following: compressive strength after 7, 14, 28 and 42 days of curing, freeze-thaw resistance. Experimental results demonstrate that it is possible to determine the optimal composition of hydraulic binders for the required strength class of the base course.

Optimization of the road binder used in the base layer in the road construction
Construction and Building Materials, 2016Co-Authors: Marek Iwański, Przemysław Buczyński, Grzegorz MazurekAbstract:Abstract The research focused on the application of mixed binder system to the Hydraulically Bound mixes used in road base (HBM). This paper presents the outcome of the tests for the mechanical characteristics of the HBM road base in terms of the binder type used. Seven binders were prepared in a laboratory by blending three primary constituents: Portland cement CEM I 32,5R, fluidised bed combustion fly ash and cement kiln dust (CKD). The proportions were selected according to the experimental design. The percent amount of the binder in the Hydraulically Bound Mixture was 6%. Two types of aggregate were used as the mineral material in the base. The composition of the Mixtures was designed based on the Proctor method. The influence of the binders on the properties of the HBM road base was evaluated by determining the compressive strength at 7, 14, 28 and 42 days of curing, frost resistance and water absorption. The test results were used to optimise the binder composition with respect to the road base characteristics and to establish the recommended road binder composition.

The effect of quarry waste dust and reclaimed asphalt filler in Hydraulically Bound Mixtures containing plasterboard gypsum and GGBS
Journal of Cleaner Production, 2020Co-Authors: Kande Bure Bai Kamara, Eshmaiel Ganjian, Morteza KhoramiAbstract:Abstract In this research, a novel Hydraulically Bound Mixture (HBM) is successfully developed using waste minerals and industrial by-products to fully replace cement in road (base) and foundation materials. HBM is a Mixture that sets and hardens by hydraulic reaction and usually has compaction by rolling. The materials used were reclaimed asphalt filler (RAF), quarry waste dust (QWD), plasterboard gypsum (PG) and ground granulated blast furnace slag (GGBS). A statistical Mixture design programme – Minitab 18, was used for the design of the experiment. Compressive strength, high pressure flow tests and freeze/thaw tests were carried out to determine the mechanical stability of the by-product binders and performance determined in the strength development by time. It was concluded that cement can be 100% replaced with the named industrial by-products. Test results revealed that the presence of GGBS is highly beneficial between 40 – 60% replacement by weight. Strength development on the hydraulic paste comprising of this GGBS replacement has a reduced strength during the first 28 days. After 28 days and up to 90 days when the maximum strength is gained, strength increases with the presence of GGBS of up to 60%. The results showed that the top four mixes in the two groups discussed in this research meet the standard requirements for road (base) and foundation materials.
