1 Dear Friends, Welcome on behalf of EvoCrete & CCL International Ltd. On short Presentation: Composite Pavement Construction with Binder Additives in Recycled Asphalt Roads By Andreas Korytowski, Germany
2 Composite Pavement Construction with Binder Additives in Recycled Asphalt Roads Global Experiences Adapted for India
3 Recycling of Asphalt Roads-Why? Rehabilitation &/or Strengthening Rehabilitation of Asphalt Pavement only! Bitumen Binders & Additives Foam Bitumen etc. Troublesome Soil! Rehabilitation & Strengthening Also! Asphalt Pavement & Top of Base Milled Aggregates-Stiff Asphalt-too Plasticy Add Cement Binder Do not forget Modifiers as EvoCrete
4 What is Modifier for Cement mixture?- EvoCrete Existing Aggregates Cement (Binder) EvoCrete (alkaline activator) Water Hydraulically -bound Material - Recycled Failed Pavements - Stabilization of any type of soils - Foundation or base of any type of infrastructure work l designed and built to last longer than 15 years
5 Binder Modifier - 100% Green EvoCrete 100 % Natural Material Certified Formulations Containing l l l l l l Special Application Edible Minerals used in Animal Feeds Delivery Minerals Used in Pharma & Fertilizers Minerals for Water Purification Gas Purification Natural Mixers & Additives Pulverized to fine mesh sizes for best binding with pozzolana cement (OPC) Added Bonding Agents in Flakes
6 How Modifier for Cement mixture works?- EvoCrete Asphalt Aggregates in Recycled Material milled Asphalt + Aggregates + if soil disintegrates faster short life. Cement only in Recycled Material water + calcium silicates and aluminates react to a hard matrix that glue together but cracks.
7 How Modifier for Cement mixture works?- EvoCrete Modified Cement & Recycled Material EvoCrete Inhibits the action of fulvic and carbonic acids. Formation of hexagonal shape crystal helps structural changes. Increases the bonding properties due to high crystal interlocking. Resulting in higher compression strength, High static & dynamic elasticity modulus and bending tensile strength. Only Cement Stabilization low crystal interlocking connectivity Modifier Cement Stabilization high crystal interlocking connectivity
8 Excellent Modifier for Cement mixture! 16 Comparison of compressive strength of cement and modified cement with EvoCrete soil & 8 % CEM I 32,5 soil & 8 % EvoCrete modifier age in days soil & 6 % EvoCrete modifier soil & 8 % CEM I 32,5 0 3,9 4,8 5,1 5,2 soil & 6 % EvoCrete modif> 0 6 6,7 8,1 8,4 soil & 8 % EvoCrete modif> 0 8 8,4 10,6 11,3
9 Excellent Modifier for Cement mixture! Comparison of bending - tensile - strength 8 6,9 7,2 6,4 6 5,9 5,3 5,1 5,6 5,6 4,7 4 2, age in days EvoCrete modifier CEM I 32,5 R
10 Why is Modifier for Cement mixture?- EvoCrete Sustainable construction Usage of site arising, recycled or artificial materials. Primary aggregate extraction and transportation is avoided. Properties of new material is superior to those of unbound granular material. Improved performance 60% thinner than unbound granular base with better performance. Reducing the thickness of the asphalt pavement layer.
11 Why is Modifier for Cement mixture?- EvoCrete Fast construction Construction methods is quick and easy (3000 to 4000 m²/day) Reducing contract duration Lower cost In-situ material, or nearby borrow-material Reduction of the cost of materials and transport No unsuitable material
12 Properties - Processing and Result High load and bearing capacity. Very resistant and durable. Reduced formation of cracks. Reduction of settlements. Impermeable, leak-proof surfaces. Acid-resistant, salt resistant. Processing possible up to -6 C and under water. Can be used for virtually any soil. Immobilization of hazardous substances. Favorable alternative to concrete technology. EvoCrete ST Ecology Purely mineral components and completely recyclable. Use of materials available on-site. Lower strain on the environment due to reduced transport. Natural surfaces no periods required for settlement. Local as is oil used. Groundwater protection.
