    • SUSTAINABLEROAD DEVELOPMENT AND MAINTENANCE SOLUTIONS
    • Project :A Proposal for the Road Development Programs of the Provinces & Citiesevolutionizing ejuvenation for arangay etter oads oads A Fast Track Road Development &Treatment Technology for Barangay, Farm-to-Market and Existing Paved Roads An Undertaking of for Rural & Urban Road Development
    • Our Mission is to contribute to the improvement and upliftment of the life- quality of the marginalized rural sector by providing an alternative solution to the traditional unpaved barangay and farm-to- market roads in their respective areas.WE MAKE WAYS…
    • The rural sector in the remote areas of our country side should be the beneficiaries of the government’s deve- lopment programs. An all-weather roadsystem can mean the difference between NEGLECT and PROGRESS.
    • OBJECTIVE To promote Cold Mix Asphalt Technology (DPWH Item 308 & 304-A) as a cost effective material and better alternative to existing gravel roads(Barangay & Farm-to-Market Roads) in the countryside and also for preventive maintenance of existing paved roads..
    • Aid in the economic and infrastructuredevelopment of the Rural & Urban Districts by introducing COLD MIX ASPHALT TECHNOLOGY as a fast track solution to gravel road upgrading, improvement and maintenance of existing paved roads.
    • Introduce the RV 200 (Micro-Mobile Asphalt Plant & Paver) as the preferredequipment used to produce and pave cold mix asphaltover existing gravelfarm-to-market and barangay roads.Use the RV 200 as an effective equipment for preventive maintenance of existing paved roads (asphalt & concrete).
    • Revolutionizing Barangay Roads
    • SEVENTY EIGHT PERCENT (78%) OF OUR NATIONAL ROADS ARE GRAVEL (UNPAVED) ROADS
    • Data gathered from the Dept. of Public Works & Highways (DPWH) shows that 157,626 kilometers (kms) of ourNational Road Network are classified as Unpaved Roads.Unpaved or Gravel Roads are mostly Municipal, Barangay and Farm to Market Roads. These roads are mostly located in the rural areas.
    • Effects ofUnpaved Roads
    • Unpaved roads are not all weatherroads - thus, it is dusty during summer and muddy during rainy season.
    • Causes undue inconvenience to farmers and local commuters.
    • Limited budget is wasted and goes only tounending maintenance (re-gravelling/grading) work instead of expansion.
    • Unpaved Gravel Roads are majorhindrances to economic growth andcreates public perception of neglect by the government.
    • THE RV 200 AS AN ASPHALT ROAD PAVER

It iseasily washed-out and deteriorates during rain downpour andtherefore cannot be compared to Cold Mix Asphalt or any otherroad pavement..

    • Common Road Problems Requiring Preventive MaintenancePot Holes Alligator Cracks Scaling
    • PREVENTIVE MAINTENANCEThere are a number of preventive maintenance procedures that includepatching, crack sealing, surface treatment and use of road rejuvenatorsthat can prolong the life of asphalt and concrete pavements.Preventive maintenance procedures can increase the pavements lifesignificantly and therefore reduce future reconstruction costs.
    • The RV 200 is designed to be the ultimate machine in preventive maintenance of asphalt and concrete pavements.
    • The RV 200 is designed toproduce DPWH Item 308 which is the most extensively used material for road patching.

    • OUR SOLUTIONWe offer the various Provinces & Cities a Sustainable Road Development Program that will : • Introduce Cold Mix Asphalt Technology as a better and cost effectivealternative to existing unpaved Gravel Roads and for preventive maintenance of existing paved roads. • Transform unpaved roads into all weather roads and rejuvenate existingpaved roads using a specially formulated Cold Mix Asphalt (DPWH Item 308 & 304A). • Optimize the budget of each Province or City for road construction and maintenance projects• Empower people to build and maintain their own roads through the concept of “bayanihan” / technology transfer – job generation. • Provide a simple inexpensive equipment to all Provinces & Cities. • Provide infrastructures to make asphalt readily available in the locality. • Assist in the evaluation of locally available material for suitability in road building.
    • PLAN OF ACTION Convince government agencies like the Dept of Public Works & Highways (DPWH), Dept of Agriculture (DA) andDept. of Agrarian Reform (DAR) that withthe use of asphalt, the benefits of an all weather and paved road could be attained and in the long run is more economical and convenient. Inform the Senators, Congressmen, Governors and Mayors to divert theirfunds from the traditional regraveling ofrural roads (barangay & farm to market) to a more logical solution provided by asphalt with a high impact on project accomplishments. Explain to them the benefits of immediately applying preventive maintenace measures to their existing roads to avoid unnecessary road construction expenses.
    • OUR PROPOSAL• We propose that each province & city adopt “PROJECT: RBR” and implement it in their locality.• Each province or city nominate a qualified contractor to implement the road projects under Project : RBR using cold mix asphalt and the RV 200.• A regular budget be allocated to facilitate funding for the road development work of the existing gravel roads in each locality, including the purchase of the needed asphalt road development materials.• Preventive maintenance of existing roads be a priority of each province or city and a substantial budget for this purpose be allocated.• Under this arrangement, Asphalt V Rock Corp. (AVRC) shall supply each province or city, through its nominated contractor, with the RV 200 under a SUPPLY-OPERATE-TRANSFER Scheme, where the nominated contractor shall exclusively undertake the implementation of the road projects under Project : RBR.
