“…In the design of MCE mixes, based on own experience [ 57 , 58 , 59 , 60 ] and information recorded in world literature [ 52 , 61 , 62 ], the percentage of cement was assumed to be 3%. The designed MCE mixes use CEM II class 32.5 Portland cement.…”

“…In the design of MCE mixes, using own experience [ 57 , 58 , 59 , 60 ] and knowledge taken from the world literature [ 65 , 66 , 67 ], the percentage of asphalt emulsion 60/40 at 5% was set. Such emulsion content allowed to obtain the total binder content in fine-grained mixtures at the level of 5.1%, and in coarse-grained mixes at the level of 4.9% (taking into account the binder contained in the emulsion and the destructor).…”

Research on the Properties of Mineral–Cement Emulsion Mixtures Using Recycled Road Pavement Materials

The reduction in natural resources and aspects of environmental protection necessitate alternative uses of waste materials in the area of construction. Recycling is also observed in road construction where mineral–cement emulsion (MCE) mixtures are applied. The MCE mix is a conglomerate that can be used to make the base layer in road pavement structures. MCE mixes contain reclaimed asphalt from old, degraded road surfaces, aggregate improving the gradation, asphalt emulsion, and cement as a binder. The use of these ingredients, especially cement, can cause shrinkage and cracks in road layers. The article presents selected issues related to the problem of cracking in MCE mixtures. The authors of the study focused on reducing the cracking phenomenon in MCE mixes by using an innovative cement binder with recycled materials. The innovative cement binder based on dusty by-products from cement plants also contributes to the optimization of the recycling process in road surfaces. The research was carried out in the field of stiffness, fatigue life, crack resistance, and shrinkage analysis of mineral–cement emulsion mixes. It was found that it was possible to reduce the stiffness and the cracking in MCE mixes. The use of innovative binders will positively affect the durability of road pavements.

“…FAC mixtures lose a significant part of the complex stiffness modulus relatively quickly and may be characterized by local decreases in stiffness, but they are still able to carry the given load in the form of strain. This is because microcracks appear in the analyzed material, which do not disqualify it for use in the layers of the road pavement base, in which such cracks are acceptable [39,40]. All tested mixtures had a similar character in the fatigue test.…”

The article presents the possibilities of using foamed asphalt in the recycling process to produce the base layer of road pavement constructions in Polish conditions. Foamed asphalt was combined with reclaimed asphalt pavement (RAP) and hydraulic binder (cement). Foamed asphalt mixtures with cement (FAC) were made, based on these ingredients. To reduce stiffness and cracking in the base layer, foamed asphalt (FA) was additionally used in the analyzed mixes containing cement. The laboratory analyzes allowed to estimate the stiffness and fatigue durability of the conglomerate. In the experimental section, measurements of deflections are made, modules of pavement layers are calculated, and their fatigue durability is determined. As a result of the research, new fatigue criteria for FAC mixtures and correlation factors of stiffness modules and fatigue durability in situ with the results of laboratory tests are developed. It is anticipated that FAC recycling technology will provide durable and safe road pavements.

Cement matrices are known from concrete testing. Cement-asphalt matrices made of cement and asphalt emulsion are used in mineral-cement-emulsion mixes (MCEM). The matric strength in MCEM mixtures has not been studied so far. Cement-asphalt matrices with 0/1 mm rubber powder are proposed by the author for use in the MCEM [3, 26]. In this paper the results of the investigation of the mechanical properties of matrices are presented for comparative purposes and for the preliminary evaluation of their suitability for MCEM. The following tests were made: indirect tensile strength, bending strength, compressive strength and rigidity modules in NAT and 4 PB-PR.
