Dukurikije imibare, hafi 80% by'imihanda minini yo mu rwego rwo hejuru yarangiye kandi ifunguye imodoka mu gihugu cyacu ni kaburimbo ya asfalt. Ariko, hamwe niterambere ryigihe, ingaruka ziterwa nikirere n’ibidukikije bitandukanye, hamwe nigikorwa cyimitwaro myinshi itwara ibinyabiziga, kaburimbo ya asfalt izagenda yangirika. Impamyabumenyi zitandukanye zo kwangirika cyangwa kwangirika bibaho, kandi gufata neza pavement ni ugukoresha uburyo bwa tekiniki bunoze bwo kugabanya iri gabanuka kugirango pavement ibashe gutanga serivisi nziza mugihe cyubuzima bwayo.

Byumvikane ko ibigo bimwe byo muri Reta zunzubumwe zamerika byasoje binyuze mubushakashatsi bwakozwe kuri kilometero ibihumbi magana yinzira nyabagendwa yo mu byiciro bitandukanye hamwe n’imibare myinshi yo kubungabunga no gusana imibare: kuri buri Yuan yashora mu kigega cyo kubungabunga ibidukikije, 3-10 Yuan irashobora kuzigama mumafaranga yo gukosora nyuma. umwanzuro. Ibyavuye muri gahunda yubushakashatsi bufatika kumihanda minini yo muri Amerika nabyo bishyirwa mubikorwa. Niba kubungabunga ibidukikije bikorwa inshuro 3-4 mugihe cyose cyubuzima bwa pavement, 45% -50% byamafaranga yakurikiranwe arashobora gukizwa. Mu gihugu cyacu, twahoraga "dushimangira kubaka no kwirengagiza kubungabunga", ibyo bikaba byaratumye umubare munini wangirika hakiri kare ku mihanda, tunanirwa kubahiriza urwego rwa serivisi rusabwa nigishushanyo, twongera ibikorwa byumuhanda ikiguzi cyo gukoresha umuhanda, kandi gitera ingaruka mbi mubuzima. Niyo mpamvu, ishami rishinzwe gucunga imihanda bireba rigomba kwita ku gufata neza imihanda minini no gukumira no kugabanya indwara zitandukanye ku muhanda, kugira ngo imihanda yacu igire serivisi nziza.
